一种用于输送滑轮的改进轮毂锁定装置，包括球形夹头，其具有位于中心的孔，用于接收轴，并具有通过其一侧延伸的轴向对准槽，允许轴上的夹头压缩，连接到滑轮末端的轮毂，并具有轴向对准的锥形孔，用于部分接收其中的轴和夹头。一种夹紧环，具有用于部分安装在夹紧环上的锥形孔，以及用于穿过夹紧环上的孔，用于穿入轮毂，并用于将夹紧环拉向轮毂，压缩夹紧环之间的夹紧环，使夹紧环压缩并接合轴、轮毂和夹紧环。
An improved hub-locking device for conveyor pulleys including a spherically shaped collet having a centrally located bore for receiving a shaft and having an axially aligned slot extending through one side thereof permitting compression of the collet on the shaft, a hub attached to the end of the pulley and having an axially aligned tapered aperture for partially receiving the collet with the shaft therein, a clamping ring having a tapered aperture for partially fitting over the collet and a plurality of bolts for passing through holes in the clamping ring, for threading into the hub and for drawing the clamping ring toward the hub compressing the collet therebetween, causing the collet to compress and engage the shaft, the hub and the clamping ring.
